The invention, although designed particularly for radiators, isobvionsly capable of application for connecting sections of various containers or conduits. 1

When-the sectionstare to be connected, at rectangularbar or slnnlar-tool (not shown) is inserted into the loose coupling member,

Thus tlielIn-azing of the member 8 to its boss is a co n mrati'rely simple matter and may be rapidly accomplished.

The radiator section may be made in various forms; that shown comprising three flutings 16, 1S and 19, the depressions being deep enough to bring the half sections into close contact with one another toallowthe use of connectingrivets 20. The end sections are closed by threaded plugs 21 received in hippls Qlhe details. of the construction may ob Eviously be changed considerably without'der parting from the spirit of the invention, and I do not; therefore, wish to be limited except as indicated by the subjoined claim;

I claim 2-- A sectional container comprising two thin metal sections havin alined openin therein and flat annular anges surronn in said openings, an outer internally threade coupling member bearing on the inner face of the flange of one of the sections, and an inner externally threaded tubular coupling member projecting through the openings in the 10 sections and bearing on the inner face ofthe flange on the other section and also being screwed into the first mentioned coupling member to draw the sections of the container together, said externally threaded coupling member havin a lug projecting inwardly therefrom and liaving a depression in its external surface corresponding thereto.

In testimony whereof I sign this specification.
